All of a sudden my charging cord won't work in the usb plug under dash on left side. It won't charge, only charges on right plug. The dealership first said I didn't know what I was talking about, then blamed it on the cords and then the phone. Because the technician said his phone charges fine, its my problem. I showed them my plugs charge fine on the right side but not on the left. Finally the guy says it must just be the data part of the cord. But why all of a sudden did it stop working? Is there a special charging cord that will work on the data portion? I have an Iphone and have used Apple cords and different brand of cords. Any suggestions? What about a magnetic cord, would that work?
